Microduino CoreRF is an AVR core board with 802.15.4 Wireless Protocol integrated. It supports any wireless modules based on 802.15.4 Protocol, including Zigbee, MAC/6LoWPAN and RF4CE.

Features

• Integrate 802.15.4 Wireless Protocol and support wireless modules like Zigbee, MAC/6LoWPAN and RF4CE.
• Small, open, stackable and economic.
• With open source hardware circuit design and Arduino compatible programming IDE.
• Like Arduino, Microduino can use ISP download method to burn programs into「bootloader」flexibly.
• With uniform Microduino interface standard and rich peripheral modules, it can easily connect with other Microduino modules and sensors.
• 2.54mm (0.1 inch) pin pitch, compatible with breadboards and pegboards.

Specification

Development

• 1.For uploading programs to Microduino CoreRF, you'll need to use Microduino-USBTTL moudle.
• 2.For IDE setup and driver installation, please refer to below:
  • Microduino Getting start

• Burn Microduino BootLoader
  • If the BootLoader fails, you need to use Arduino UNO or the other Microduino board to burn bootloader for the broken Microduino.
  • Users can refer to the tutorial: How to use Arduino UNO to burn BootLoader into Microduino-Core?。

Test

Use program examples in ZigduinoRadio library to test.

void loop() 
{ 
    if (Serial.available()) 
    { 
        ZigduinoRadio.beginTransmission(); 
 
        Serial.println(); 
        Serial.print("Tx: "); 
 
        while(Serial.available()) 
        { 
            char c = Serial.read(); 
            Serial.write(c); 
            ZigduinoRadio.write(c); 
        } 
 
        Serial.println(); 
 
        ZigduinoRadio.endTransmission(); 
    } 
 
    if (ZigduinoRadio.available()) 
    { 
        Serial.println(); 
        Serial.print("Rx: "); 
 
        while(ZigduinoRadio.available()) 
            Serial.write(ZigduinoRadio.read()); 
 
        Serial.println(); 
        Serial.print("LQI: "); 
        Serial.print(ZigduinoRadio.getLqi(), 10); 
        Serial.print(", RSSI: "); 
        Serial.print(ZigduinoRadio.getLastRssi(), 10); 
        Serial.print(" dBm, ED: "); 
        Serial.print(ZigduinoRadio.getLastEd(), 10); 
        Serial.println("dBm"); 
    } 
 
    delay(100); 
} 
 
void errHandle(radio_error_t err) 
{ 
    Serial.println(); 
    Serial.print("Error: "); 
    Serial.print((uint8_t)err, 10); 
    Serial.println(); 
} 
 
void onXmitDone(radio_tx_done_t x) 
{ 
    Serial.println(); 
    Serial.print("TxDone: "); 
    Serial.print((uint8_t)x, 10); 
    Serial.println(); 
}

This example realizes wireless serial transmission function. Since the CoreRF adopts serial port download, you need firstly stack a Microduino-USBTTL on it: Choose Microduino CoreRF as the board card

Open the serial monitor after uploading programs to the two Core-RF modules, input " Hello Microduino!", click "Send" and you'll get the following result:

By here, we've completed the test.
